SPECIFICATION formingpart of Letters Patent No. 734,776, dated July 28, 1903. Application filed May 7,1902. Serial l lo. 106,337. (No model.)

To all whom it may concern.- I Be it known thatl, J AMEs TIMMS, of Columbus, in the county of Franklin and State of Ohio, have-invented certain new and useful Improvements in Oar-Couplings; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

, My invention relates to an improvement in car-couplings, and is designed particularly as an improvement on the coupling shown in means which when operated will throw the knuckle and which can be so set as to permit the knuckle to be opened by a pull thereon.

With these ends in view my invention consists in the parts and combinations of parts, as will be more fully explained, and pointed out in the claims. I

In the accompanying drawings, Figure l is a view in side elevation, partly broken away, of a coupling embodying my improvements. Fig. 2 is a top plan view of same. Fig. 3 is a view of the locking-block removed, and Fig. 4 is a view showing the locking-block set and also the locking-block-actuating mechanism.

1 represents the coupling-head, to which is pivotally connected the knuckle 2 by a pin 3, and said knuckle 2 being provided on its inner end with a tail 5, curved approximately concentric with the axis of the knuckle, and. the coupling is made with a hollow enlargement 6 to receive the tail of the knuckle when the latter is closed.

7 represents the angular locking-block, which is mounted to move in a chamber Sin the coupling-head and is confined and oper- W which opening islocated toone side of the center of the block 7, so as to give a lateral as well as a vertical pull on the block to tip ittto an inclined position, as will more fully hereinafter appear.

It is apparent that instead of locating the opening 10 in the head to one side of the center of the block 7, so as to cause the lever 9 to fulcrum thereagainst during the lifting movement of the block, which is essential in order to tiltthe block, the same result could be accomplished by locating the opening 10 over the center of the block and providing the lever with an enlargement on its righthand side, as shown in dotted lines, which enlargement, engaging the side wall of the opening, would produce precisely the result accomplished by locating the opening to the left of the center of the locking-block. A

Pivotally secured in the upper end of the lever is the link 10. This link is mounted to swing in a plane transversely of the head of the coupling, and while it is free to fall to a horizontal position to the right of the lever 9 it is restrained from falling to the left by the stop 10. Hence when the parts are in repose with the locking-block either set or in a position'to lock the knuckle the lever rests against the left-hand side of the wall of the opening 10, while the link 10 rests in approximately ahorizontal plane, with its free end pointing toward the right, thus always preventing the possibility of any entanglement or twisting of the chain to which the free end of the link is connected. 7 This chain 9 is connected at its upper end to the free end of the actuated lever 9 This lever 9 is mounted on the carbody in any approved manner and its inner bent end extends outwardly overthe couplinghead in a plane slightly to the right of the center of the opening 10, so that an upward pull on the chain moves the lever 9 in contact with the right-l1and side of the wall of the opening 10, thus forcing the locking-block toward the left for a purpose which will hereinafter be explained. The block 7 is provided at its lower end with the toe or shoulder 12, which latter is slightly beveled or undercut to engage the seat 19, formed integral with thehead below the plane of the tail of the knuckle, so as to positively retain the locking-block in its elevated position or set against accidental'displacement. The block is made with a vertical roo groove 13 to receive a tonguelet on the knuckle and securely lock the same in the head. The,

' of the knuckle to pass freely between a beveled or inclined lip 16 at the lower end of the block and a shoulder 17, formed by the recess in the block and located about midway between the ends thereof,for a purpose which will more fully hereinafter appear.

When it is desired to open the knuckle, the chain 9 is pulled upward to lift block 7, drawing the grooved portion 13 thereof free from the tongue 14, and when the tail 5 of the knuckle alines with the recessed portion 15 of the block a further upward pull on the chain will draw the lip 16 against the beveled or inclined lower face of the tail 5 and owing to the cam action of the lip 16 against the tail of the knuckle and by the leverage due to the relative locations of the lip 16 and the pivotal point of the knuckle throw the latter to its extreme open position. WVhen the pull on the chain is released, the shoulder 17 will rest on the knuckle-tail and remain thereon until the knuckle is closed, when the block will fall into its locked position, above described.

If cars are coupled together and it is desired to unlock the knuckle without opening the same, the block 7 is drawn up far enough to aline the tail of they knuckle with the recessed portion 15 thereon, the lever 9 exerting a lateral as well as a vertical pull on the block, tilting it and pulling the lip 12 over onto the seat 19, and as the lip 12 and the seat I 19 are slightly inclined the block will be retained in this inclined position, and thereby make it difficult to shake or jar it from its seat.

As the cars pull apart the upper inclined surface of the tail engages the shoulder 17 and lifts the block from its seat 19 and carries it away from 19. The outer edge of the tail also may be made to move the block away from its seat. I-lence after the block has been upward incline on its upper face, this is not by any means essential, as the pressure of the outer edge of the tail against the lockingblock is sufficient to unseat the block without any lifting of the latter.

It is evident that many slight changes might be resorted to in the relative arrangement of parts herein shown and described without departing from the spirit and scope of my invention. Hence I would have it understood that I do not wish to limit myself to the exact construction and arrangement of parts shown and described; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. The combination with a coupling-head having an opening through its top and apivoted knuckle located within said head, of a ;locking-block, a lever secured to the top of ;the block and constructed to engage the side Ewall of the opening in the head, an actuatinglever located in a plane adjacent to the side jwall of the opening engaged by the lever on the block and means connecting the two levers.

2. The combination with a coupling-head and a pivoted knuckle, of a locking-block, a lever loosely connected to the upper end of said block and passing through an opening in the top of the head, an actuating-lever lo- ,cated in a plane to one side of the lever pivoted to the block and loose connections between the two levers.

3. The combination with a coupling-head and a pivoted knuckle, of a locking-block a lever loosely connected to the upper end of said block, a link pivoted to the upper end of the lever and free to swing over laterally in'one direction, and an actuating-lever the outer end of which is located in a vertical plane with and above the laterally-swinging link and connected to the latter.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

JAMES TIMMS.
